2017 Chicxulub Revealed THE UNIVERSITY TEXAS OF AUSTIN AT JACKSON• SCHOOL GEOSCIENCES OF 2017 NEWSLETTER• Newsletter2 017 Chicxulub Revealed A first look at rocks from the crater left by the asteroid that wiped out non-avian dinosaurs WELCOME Dear Alumni and Friends he devastation that Hurricane Harvey brought to Texas communities in August was a tragic reminder of how vital it is to understand our planet and T its processes. Shortly after the hurricane struck, our scientists, through our Rapid Response program, began to conduct research to understand how Harvey has impacted the coast and offshore Gulf of Mexico. This research will help determine the best ways to deal with many coastal issues in the aftermath of the storm, and how we might better prepare for such events in the future.

This is what we strive to do here at the THE CHICXULUB CRATER FORMED BY THE Jackson School of Geosciences. This year’s Newsletter holds some tremendous examples.

Here again, these are large scientific missions with breadth and depth few schools could match. It has been a successful year of science and education at the Jackson School, but one also punctuated by loss. We lost a tremendously talented researcher and friend with the passing of Kirk McIntosh, and a giant in the field with the passing of former UT President and Bureau of Economic Geology Director Peter Flawn. They will be sorely missed, but not forgotten. You will find a memorial to each in the back of the Newsletter. Many of our own in the Jackson School family live and work in communities ravaged by Harvey. We hope that reading this year’s Newsletter will give you a little respite from the hard work of putting your homes and lives back together. We also hope it will make you proud to be part of the Jackson School family. We are thinking of you, and you will continue to be in our thoughts.

Placing World War I in the History of Mathematics David Aubin and Catherine Goldstein Abstract. In the historical literature, opposite conclusions were drawn about the impact of the First World War on mathematics. In this chapter, the case is made that the war was an important event for the history of mathematics. We show that although mathematicians' experience of the war was extremely varied, its impact was decisive on the life of a great number of them. We present an overview of some uses of mathematics in war and of the development of mathematics during the war. We conclude by arguing that the war also was a crucial factor in the institutional modernization of mathematics. Les vrais adversaires, dans la guerre d'aujourd'hui, ce sont les professeurs de math´ematiques`aleur table, les physiciens et les chimistes dans leur laboratoire.

ARTICLES It’s Not About the Money: THE ROLE OF PREFERENCES, COGNITIVE BIASES, AND HEURISTICS AMONG PROFESSIONAL ATHLETES Michael A. McCann† I. INTRODUCTION Professional athletes are often regarded as selfish, greedy, and out-of-touch with regular people. They hire agents who are vilified for negotiating employment contracts that occasionally yield compensation in excess of national gross domestic products.1 Professional athletes are thus commonly assumed to most value economic remuneration, rather than the “love of the game” or some other intangible, romanticized inclination. Lending credibility to this intuition is the rational actor model; a law and economic precept which presupposes that when individuals are presented with a set of choices, they rationally weigh costs and benefits, and select the course of † Assistant Professor of Law, Mississippi College School of Law; LL.M., Harvard Law School; J.D., University of Virginia School of Law; B.A., Georgetown University.

This pretensión can rarely be advanced in favour of familiar letters, written in haste for the information or entertain­ ment of private friends. Such letters are frequently among the most delightful of literary compositions, but the stamp of absolute literary perfe&ion is rarely impressed upon them. The exceptions to this rule, in English literature at least, occur principally in the epistolary litera­ ture of the eighteenth century.

    ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter.
